If unhealthy pull them off. Look up a natural spray for leafy veggies.

Can I harvest rhubarb all summer in zone 3a safely? I read recently that late summer harvests are poisonous . I’ve heard and have been practicing harvesting 1/3 or less of the plant at a time. Then I wait 2 weeks before harvesting again all summer long. I have big healthy beautiful plants that are over 20 years old.

I read that kangarhu rhubarb is good for zone 9B. They are heat tolerant I'm going to try one.

Did you actually try to grow KangaRhu? I love rhubarb but don’t want to waste my $$ if you had any advice. I’m in 9a. Thanks in any help.

Rhubarb can be very variable. I have seen both short and long stemmed rhubarb in the shops. I have also seen some with mostly green stems and some that are deep red for their full length. As most rhubarb is grown from seed, and there are also a number of different varieties, this variation is inevitable. at a house where we used to live the soil was very rich and we had thick, deep red stems that were about 600 mm (24") long. We shifted to another town with a slightly different climate and soil that still needs improving more and the stems are still a good colour but not as long.
